PidKeyTool was tested and does not give proper results about pidkeytool HOT 4 CLOSED

from pidkeytool.

The best way to determine whether the key is valid is to use Fiddler capture and analysis. The premise is that it must be tested on a PC that has not been activated. PidKeyTool is a tool written in this way.

So basically what you have proven is exactly what I said. When you entered your test key 2QN4X-M2J4M-HFGR4-YXK7D-63BP6 (Windows 10 Pro Retail key good for 1 activation) in https://pidkeys.com this key was tested on their virtual server and it told you it was ONLINE (Online key error code message means the key was NEW at the time of testing) since their virtual server was able to activate it resulting in a "Error code: Online key". Then when you went to activate again by using Change Product Key in your Windows operating system after this key was tested on https://pidkeys.com it gave an error 0xC004C008 and this error means that the key is used more than the allowable limit.

I now tested this same key 2QN4X-M2J4M-HFGR4-YXK7D-63BP6 in https://pidkeys.com (refer to screenshot) and now it gives the same 0xC004C008 error as when you tried to activate it meaning the key was BURNED/USED immediately after you tested this key on https://pidkeys.com since this site uses a virtual server to activate keys in order to obtain Error code status results.

So I have CLEARLY PROVEN that there is no tool (program, app, or website) that exists that can give you the status of a Microsoft Windows key WITHOUT BURNING/USING 1 activation count from that key.

1. Original 0xC004C008 remain max times is 5-20 times.
2. Detect 0xC004C008 key is not possible to consume the remaining times. Unless the CID has been obtained.
3. This key I ever tested at 2022/11/26 for the result is 0xC004C008.
   
4. Yesterday some 008 keys maybe became online keys on this site , but today, some online keys may turn into 0xC004C008 on this site.
